OIL-SPRAYING DEVICE.

Application filed August 11, 1924. Serial No. 731,416.

The invention relates to gas making apparatus, such as carburetted Water gas sets and has for its objects to provide a water cooled oil spray of, novel and improved construction and arrangement, which is designed to be used in conjunction with the elements of the apparatus during the manufacture of water gas and the like.

During the steam run or gas making period in the cycle of operation of a water gas set, oil is sprayed into the carburetor for the purpose of enriching the blue water gas, which passes over into the carburetor from the generator. This may be accomplished by lowering the oil spray into the carburetor and opening the valve in the oil line leading to the spray. The valve in the oil line is opened and closed at the proper intervals to admit the required amount of oil 0 at a predetermined rate of flow. After passing through the valve, the oil is carried by the oil pipe line to the spray head, where the oil is atomized into and mixed with the blue gas that enters the carburetor from the generator. At the termination of the gas making period the oil supply is out off by closing the valve and in the event that the oil spray is not water cooled, it is generally raised up or removed from the carburetor during the air blasting period when no oil or steam is passing through, and the spray is replaced in position for the succeeding run at the termination of the blasting period. If not properly cooled or otherwise protected from the heat in the manner described, the sprays soon corrode and become plugged up, with the result that the spray of oil is seriously affected and impaired. If the oil spray is of a movable character certain disadvantages are present in that studing boxes, swivel joints or flexible hose are required, all of which are highly susceptible to leakage, resulting in loss of oil as well as an appreciable fire hazard. These faults also impair the general efficiency of the apparatus and the quality of gas produced.

In order to eliminate the disadvantages hereinabove stated an object of the present invention is to provide a self-contained water cooled oil spray which when clamped on the carburetor of the gas making set, is designed'to remain in its operative position during both the blasting and gas making periods.

A further object of the invention is to provide a Water cooled oil spray of a highly efficient character, composed of few parts of economical manufacture, and which when assembled results in a complete and self-contamed unit capable of convenient and secure attachment on the carburetor of a gas making set, and Which may be readily removed when desired for cleaning or repairs.

A further and important object of the invention is to provide an oil'spray of the character described which is readily adjustable to various degrees of insertion within the carburetor of the gas making apparatus, :CCOI'CllIlg to the requirements of manufacare.

In addition to the general objects recited above, the invention has for further objects such other improvements and advantages in construction and operation as are found to obtain in the structures and devices hereinafter described or claimed.

In order to make the invention more clearly understood there are shown in the accompanying drawings means for carrying the same into practical effect, without limiting the improvements, in their useful applications, to the particular constructions which, for the purpose of explanation, have been made the subject of illustration.

In said drawings:

Figure 1 is a vertical sectional view through the upper portion of the carburetor of a. water gas set and showing a water cooled spray constituting a preferred embodiment of the invention, in position thereon.

Fig. 2 is a side elevation of the assembled oil spray illustrated in Fig. 1.

Fig. 3 is a transverse section on line 3--3 of Fig. l; and

Fig. 4 is an enlarged detail view in vertical section of the oil spray head.

Referring to the drawings, 1 indicates the upper portion of the carburetor of a gas making apparatus, which may be of any de- 100 sired or preferred construction and which is preferably provided with a. dome 2 having positioned thereon a cover plate 3. The plate 3 is provided with a central depressed portion 4 surrounding an aperture 5 through 105 which the cylindrical water jacket 6 of the oil spray unit is adapted to loosely project. The jacket 6 may be constructed of a piece of steel pipe having at its lower end a welded-in bottom portion 7, centrally aper- 110 tured as at 8 to permit the spray of oil therethrough into the carburetor. The upper portion of the cylindrical water jacket 6 has Welded or otherwise rigidly secured. thereto a pair of diametrically opposed upwardly projecting bolts 9 which are suitably threaded at their upper ends. The oil supply-pipe- 10 is adapted to project downwardly ,intothe jacket 6 and has threaded ontoits lower end a spray head 11 having a nozzle portion 12 adapted to register with the aperture 8. The oil supply pipe 10 communicates with the usual valve controlled oil supply (not shown) and has welded or otherwise per manently secured thereto an apertured plate 13 having diametrically opposed ears or lugs 14 which areapertured as at 15 to loosely receive the upper ends or the threaded bolts 9. A gasketfl6, preferably of copper, is in terpo'sed-between the spray head 11 and the bottom 7 ofthe pipe or jacket 6 and it will be apparent thatflby drawing down on'the nuts 17 the spray head may'be clamped tightly down upon the gasket 16 to provide a water-excluding engagement with the bottom of the water jacket. 7 i j j A split collar18 is' 'adapted to be securely and adjustably clamped inany desiredposition on the jacket 6 by means of the bolts 19 passing through the apertured ears 20 of the split collar member and secured thereto by the nuts 21. Thesplit collar is provided with a lower annular flange portion 22 adapted to nest within the central depressed portion 4 ot-the cover plate 3' and the assembled oil sprayunit may be'rigidly secured in position by means of the bolts 23 and nuts 23*, the former being threaded or otherwise secured at their lower ends to the cover plate .3 on opposite sides of the depressed portion 4, and having loosely fitted thereupon a'pair of clampingmembers 24. When the spraying unit is'assembled the cylindrical jacket 6 projects looselydownward through the aper'- ture 5 of the cover plate 3 and by tightening the nuts 23 the ends of the clamping members 24 are drawn securely down upon the annular flange portion 22 of the split collar member 18, a suitable packing or gasket 25 such as copper and asbestos, being interposed between the collar and the cover plate to insurea fluid tight. seal.

' It will be apparent that the construction described permits or any distance of insertion of the'oil spray'into the carburetor by reason of'the' adjustability of the collar 18 on the jacket or pipe 6. The oil spray unit may be removed from the carburetor for cleaning or repairs by loosening the nuts 23 and turning the clampingmembers .24 approximately 90*degrees to release their ends from engagement with the collar 18; j

The water. supply for the jacket 6' is ad m tted from an inlet pipe 26 projecting downwardly 1nt0 the jacket and is controlled gagement with the gasket 16.

by the valve 27 and a water outlet port 28 located nearthe upper portion of the acket 6 may be connected to any desired point of 32 and a shouldered portion 38 designed to register with the aperture 8 in the bottom of the water jacket 6. A second shouldered portion" 34 is preferablyprovided for enlt will be apparent that the construction and arrangement above described provides an efiiciently cooled, rigid and self-contained oil spray unit, which'is susceptible of convenie'nt adjustmentior any distance of insertion and which may be readily removed from the apparatus when desired for cleaningor repairs. The deviceis composed of few parts which when assembled, positively insure against the leakage of water from the jacket, or gas or fluid from the carburetor."
